May 22, 2024 · The surface area of a rectangular prism calculator gives us the answer: A = 2 × l × w + 2 × l × h + 2 × w × h = 2 × 8 ft × 6 ft + 2 × 8 ft × 5 ft + 2 × 6 ft × 5 ft = 236 ft². But that is the surface area of the entire prism, and we don't want to tile it all around. After all, if we tile the top, it would be pretty difficult to get ...

The surface area of a rectangular prism is the total area or region covered by its six faces. If l, b, and h are the length, breadth, and height of a rectangular prism, then: Its total surface area (TSA) = 2 (lb + bh + lh) Its lateral surface area (LSA) = 2h (l + b) Prisms are solids with flat parallelogram sides and identical polygon bases.

Label the length, width, and height of your rectangular prism. Each rectangular prism has a length, a width, and a height. Draw a picture of the prism, and write the symbols l, w, and h next to three different edges of the shape.[2] X Research source If you're not sure which sides to label, pick any corner. Label the three lines that meet at that corner. For example: A box has a base that ...Look at the six faces of the prism. To cover the whole surface area, you'd need to paint six different "faces." Think about each one — or find a box of cereal and look at them directly:[3] X Research source There are a top and bottom face. Both are the same size.[4] X Research source There are a front and a back face. Both are the same size. There are a left and right face. Both are the ...Find the area of the bottom face. To start out, let's find the surface area of just one face: the bottom. This is a rectangle, just like every face. One edge of the rectangle is labeled length and the other is labeled width. To find the area of the rectangle, just multiply the two edges together.[6] X Research source Area (bottom edge) = length times width = lw. Going back to our example, the ...Find the area of the top face. Wait a second — we already noticed that the top and bottom faces are the same size. This must also have an area of lw[7] X Research source . In our example, the top area is also 12 square inches.Find the area of the front and back faces. Go back to your diagram and look at the front face: the one with one edge labeled width and one labeled height. The area of the front face = width times height = wh. The area of the back is also wh. In our example, w = 3 inches and h = 5 inches, so the area of the front is 3 inches x 5 inches =15 square inches. The area of the back face is also 15 ...Areas always use "square units," like square inches or square centimeters.[12] X Research source A square inch is just what it sounds like: a square that's one inch wide and one inch long. If a prism has a surface area of 50 square inches, that means it takes 50 of those squares to cover every surface on the prism. Thanks Helpful 0 Not Helpful 0If you don't know which way up the prism is, you can call any side the height. The length is usually the longest side, but even that's not really important. As long as you stick with the same names for the whole problem, you'll be fine.[13] X Research source Thanks Helpful 1 Not Helpful 0Some teachers use "breadth" or "depth" instead of one of these names. That's fine, as long as you label each side clearly. Thanks Helpful 0 Not Helpful 0- 1.3M
The total surface area of a rectangular prism is 96 ft2 with a base area of 12 ft2 and the perimeter of the base being 18 ft. Determine its height of the rectangular prism. Solution: Base Area = Top Area = lb = 12 ft 2

The surface area of a rectangular prism is the total area of all of the faces of a rectangular prism. Rectangular prisms have three pairs of identical faces – top and bottom, front and back, and left and right. Notice that it is always the opposite faces that are identical. Rectangular prisms are also known as cuboids.
The surface area of a rectangular prism can be broken up into two parts: lateral surface area and total surface area. The total surface area is the surface area of all of the faces of a rectangular prism and is given by the formula. where l is length, w is width, and h is height.
